Confirmed , this makes FF "useless"

Attachment: fix

See https://bugzilla.mozilla.org/show_bug.cgi?id=317375#c110. I had a fix for this in one version of my patch but somehow it dropped out.

It works on the older hourly build

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20060125 Firefox/1.6a1 ID:2006012517

But as have said, it doesn't work on the 0126 nightly build.

The patch of this bug caused the close buttons on tabs not to work anymore, if tabs have a fixed width by means of this .css:

.tabbrowser-tabs > hbox {
  display: block !important;
}

.tabbrowser-tabs tab {
  min-width: 100px !important;
}

At least, in the 2006012621 build they stopped working.

There's a lot more weirdness if you fix the width
-flickering [X] when you hover over it
-doubleclick on tabbar doesn't work
-height misrendering of the tabs

(caused by display:block ?)

You need to file a new bug for this, cc me pse

something to try = try clicking your mouse wheel on-off a few times (i.e., the middle button) and/or open your mouse control panel, change the mouse wheel settings, and save the new settings. why? read these 2 bug reports: 

From:  Bug 465259 -  firefox randomly stops responding to mouse clicks  
  -------  Comment #2 From  Brandon Mitchell   2009-07-16 13:34:11 PDT  -------

I experienced this issue yesterday for the first time, after upgrading from FF3
to FF3.5 a few weeks ago, and I believe (but am not certain) that I was able to
fix the problem by middle clicking on the scrollbar to activate and then
deactivate autoscroll. (Actually I used an AutoHotkey mapping of the left
Windows key to the middle mouse button; I don't have a mouse and my touchpad
doesn't have a middle button.) Today I have been unable to reproduce the
phenomenon. On the one hand, I wish I knew how to reproduce this bug; on the
other hand I sincerely hope that I don't encounter this nasty business again.

Based on my reading of support forum pages (first two of the three URLs pasted
below), I wildly conjecture that this might possibly be related to the middle
mouse button somehow. Some posters have suggested that it is due to a driver
problem or a mechanical problem such as a stuck middle mouse button, but
posters also point out that the problem seems to be specifically related to
Firefox 3.x software. One person (see third URL pasted below) claims that he
still had the problem after installing a new mouse.

There are at least two or three other
"Firefox-won't-respond-to-mouse-clicks-unless-I-switch-focus-to-another-app-window"
bugs that might be duplicates of this one: Bug 442572, Bug 451116, Bug 483254.

I have solved the problem for myself. It was not a bug, but a mechanical
problem. Nevertheless Firefox is the only browser that seemed to be affected:

My middle mouse button was not working. I realized that, when I opened Excel
and found the program selecting multiple cells as if I kept pressing the left
mouse button.

I opened my mouse and found that the little mechanical transmitter for the
middle mouse button (wheel)was jammed. I released it and now everything works
fine.
